Free trade and protection

1. Overview

Free trade is the international exchange of goods and services without government-imposed restrictions such as taxes or volume limits. It is based on the principle that countries should specialize in producing goods where they have the lowest opportunity cost, leading to increased global output and lower prices. Protectionism is the opposite policy, where a government uses trade barriers to restrict imports. Governments use protectionism to shield domestic industries from foreign competition, preserve local jobs, and manage the Balance of Payments. The tension between these two approaches dictates how nations interact in the global economy and affects the cost of living for every consumer.

Key Definitions

• Free Trade: A policy where a government does not discriminate against imports or interfere with exports by applying tariffs (to imports) or subsidies (to exports).
• Protectionism: The practice of shielding a country's domestic industries from foreign competition by taxing or limiting imports.
• Tariff: A tax imposed on imported goods. It increases the cost of the import to the consumer and generates revenue for the government.
• Quota: A physical limit on the quantity or volume of a specific good that can be imported into a country over a set period.
• Subsidy: A financial payment made by the government to domestic producers. This lowers their production costs, allowing them to sell at a lower price and compete more effectively against foreign imports.
• Embargo: A complete government ban on trade with a particular country or the sale of specific products (often for political or safety reasons).
• Dumping: The act of a foreign company exporting a product at a price lower than its cost of production or lower than the price charged in its home market to eliminate competition.
• Infant Industry: A new, developing industry that lacks the economies of scale necessary to compete with established foreign rivals and requires temporary protection to survive.
• Sunset Industry: An older, declining industry that is no longer internationally competitive but may be protected to prevent sudden, large-scale structural unemployment.

Core Content

A. The Concept of Free Trade

Free trade operates on the logic of efficiency. When countries trade without barriers, they can focus their resources on industries where they are most productive.

• The Mechanism: In a free trade environment, the price of a good is determined by the World Price ($P_w$). If the world price is lower than the price a domestic country could produce it for, the country will import the good.
• Impact on Consumers: Consumers benefit from the lowest possible prices and a wider variety of products. Competition from abroad forces domestic firms to be more innovative and efficient.
• Impact on Producers: Efficient domestic firms gain access to much larger global markets, allowing them to achieve economies of scale (lower average costs due to high-volume production). However, inefficient domestic firms may go out of business.

Evaluation of Free Trade:

• Advantages:
  • Lower Prices: Increased competition and lack of tariffs keep costs down for households.
  • Specialization: Countries produce what they are best at, increasing total global output.
  • Economic Growth: Access to larger markets boosts export revenue and GDP.
• Disadvantages:
  • Structural Unemployment: As inefficient domestic industries close, workers lose jobs and may lack the skills to move into new industries.
  • Over-dependence: Countries may become too reliant on others for essential goods (e.g., food or energy).

B. Protectionism Method 1: Tariffs

A tariff is the most common tool of protectionism. It acts as a tax on the consumer of the imported good.

• The Chain of Reasoning:
  1. Government imposes a Tariff.
  2. The price of the imported good rises in the domestic market.
  3. Quantity demanded for the import contracts (falls).
  4. Domestic consumers switch to relatively cheaper domestic substitutes.
  5. Domestic production increases, protecting local jobs.
• Government Revenue: The government collects the tariff amount for every unit imported. This is a source of tax revenue.

Evaluation of Tariffs:

• Pros: Protects domestic employment; generates government revenue; reduces the Current Account deficit by lowering import spending.
• Cons: Higher prices for consumers; domestic firms may become "lazy" and inefficient without competition; risks retaliation where other countries tax your exports in return.

---

C. Protectionism Method 2: Quotas

A quota restricts the quantity rather than the price.

• The Mechanism: Once the physical limit of an import is reached (e.g., only 100,000 foreign cars per year), no more can enter the country regardless of demand.
• Impact: Because the supply of the import is restricted, the price of the import usually rises due to the shortage.

Evaluation of Quotas:

• Pros: Provides absolute certainty to domestic firms about the maximum amount of foreign competition they will face.
• Cons: Unlike tariffs, the government receives no tax revenue. Consumers face higher prices and potential shortages.

---

D. Protectionism Method 3: Subsidies

Subsidies are "positive" protectionism because they help domestic firms by lowering costs rather than by taxing foreigners.

• The Mechanism: The government gives money to local firms (e.g., US$10 per ton of wheat). This shifts the Domestic Supply Curve to the right.
• Impact: Domestic firms can now lower their prices to match the world price while still making a profit. Domestic production increases, and imports decrease.

Evaluation of Subsidies:

• Pros: Does not increase prices for consumers (prices may even fall); helps domestic firms compete globally; protects jobs.
• Cons: High opportunity cost (the money could have been spent on education or healthcare); requires high levels of taxation to fund; may protect inefficient firms that should otherwise fail.

E. Summary Table: Arguments for Protectionism

Argument	Logic	Evaluation/Drawback
Infant Industry	Protects new firms until they grow and gain economies of scale.	Firms may become dependent on protection and never become efficient.
Anti-Dumping	Prevents foreign firms from selling below cost to bankrupt domestic rivals.	Difficult to prove if a price is "too low" or just the result of high efficiency.
Employment	Prevents job losses in industries threatened by cheap imports.	Prolongs the life of "sunset" industries; prevents labor from moving to more productive sectors.
Strategic Interests	Ensures the country can produce its own food, steel, or energy for national security.	Leads to higher costs for the economy in the long run.
Balance of Payments	Reduces spending on imports to improve the Current Account balance.	May lead to retaliation, which reduces export revenue, cancelling out the benefit.

Worked example 1 — Analyzing the Impact of a Tariff

Question: Describe how the imposition of a tariff on imported televisions affects domestic consumers and the government.

Model Answer: A tariff is a tax on imported goods. For domestic consumers, the tariff increases the market price of imported televisions. This leads to a contraction in demand for imports and a reduction in consumer surplus, as households must either pay more for the same television or switch to a less-preferred domestic alternative. Consequently, the cost of living for these consumers increases.

For the government, the tariff serves as a source of revenue. For every unit of television still imported after the tax is applied, the government collects the tariff value. This revenue can be used to fund public services or reduce other taxes. However, the government must consider the risk of retaliation from trading partners, which could hurt domestic exporters in other sectors.

Worked example 2 — Evaluating Protectionist Measures

Question: Explain why a government might prefer using a subsidy rather than a quota to protect its domestic farming industry.

Model Answer: A government might prefer a subsidy because it does not result in higher prices for consumers. While a quota restricts the supply of food and forces prices up, a subsidy lowers the production costs for domestic farmers. This allows farmers to increase their supply and compete with world prices, keeping food affordable for low-income households.

Furthermore, a subsidy encourages domestic production and protects rural employment without causing the shortages often associated with quotas. However, the government must weigh this against the opportunity cost. Subsidies are funded by taxpayers, meaning the money spent on farmers is unavailable for other areas like infrastructure or healthcare. In contrast, a quota costs the government nothing to implement but places the financial burden directly on the consumer through higher prices.

Extended Content (Extended Only)

While this topic is Core, Extended students must be able to perform a Stakeholder Analysis when evaluating trade policy.

• Winners of Protectionism: Domestic producers (higher revenue), Domestic workers (job security), Government (revenue from tariffs).
• Losers of Protectionism: Domestic consumers (higher prices, less choice), Foreign exporters (lost sales), Domestic firms using imported raw materials (higher costs of production).

Key Equations and Numerical Facts

• Price to Consumer (Tariff): $World Price + Tariff$
• Government Revenue: $Tariff \times Quantity\ of\ Imports$
• Domestic Consumption: $Domestic\ Production + Imports$
• Effect of Subsidy: $New\ Cost\ of\ Production = Old\ Cost - Subsidy\ per\ unit$

Common Mistakes to Avoid

• The Balance of Payments Trap: Students often think protectionism always fixes a trade deficit. Correction: If you impose a tariff, other countries may retaliate with their own tariffs. This causes your exports to fall, which can worsen the Balance of Payments.
• Revenue Confusion: Remember that Tariffs provide government revenue, but Quotas and Embargoes do not. Subsidies actually cost the government money.
• Import Quotas and Expenses: Know that fewer imports arise from shrinking an import quota. This cuts import expenses (money flowing out of the country) and therefore shrinks a balance of payments shortfall (improves the Current Account).
• Efficiency vs. Jobs: Don't just say protectionism is "good" because it saves jobs. You must balance this by mentioning it protects inefficiency and raises costs for everyone else.

Exam Tips

• Chain of Reasoning: In "Analyse" questions, use step-by-step logic. Example: "A subsidy lowers costs $\rightarrow$ Supply shifts right $\rightarrow$ Domestic price falls $\rightarrow$ Imports become less attractive $\rightarrow$ Current Account improves."
• The "Depends On" Factor: When evaluating, use phrases like "The success of a tariff depends on the Price Elasticity of Demand (PED) for the import. If demand is inelastic, consumers will keep buying the import despite the tax, and the trade deficit may not improve."
• Stakeholder Perspective: Always look at the policy through the eyes of the Consumer, the Producer, and the Government. This ensures a balanced, high-mark evaluation.
• Graph Accuracy: If asked to describe a tariff diagram, remember the tariff line is always above the world price line, and the gap between domestic supply and demand narrows (meaning fewer imports).

(a)

1. Quotas: A quota is a limit on the quantity of a good that can be imported. [B1] Definition of a quota. By restricting the amount of imported steel, Gamma can protect its domestic producers from competition. [B1] Explanation of the impact on domestic producers.
2. Embargoes: An embargo is a complete ban on the import of a particular good from a specific country. [B1] Definition of an embargo. Gamma could impose an embargo on steel imports from a country it deems to be engaging in unfair trade practices. [B1] Explanation of a possible justification for an embargo.

(b) Arguments for trade restrictions:

1. Protection of domestic jobs: Trade restrictions can protect jobs in the domestic steel industry by making imported steel more expensive. [B1] Explanation of job protection. This can reduce unemployment and boost domestic demand. [B1] Explanation of the macroeconomic impact.
2. National security: A strong domestic steel industry is important for national security, as steel is used in many military applications. [B1] Explanation of national security argument. Trade restrictions can ensure that Gamma has a reliable supply of steel in times of crisis. [B1] Explanation of the impact on steel supply.

Arguments against trade restrictions:

1. Higher prices for consumers: Trade restrictions increase the price of steel, which can harm consumers and businesses that use steel in their production processes. [B1] Explanation of the impact on consumers. This can reduce competitiveness and lower living standards. [B1] Explanation of the impact on competitiveness.
2. Retaliation from other countries: Trade restrictions can lead to retaliation from other countries, who may impose trade restrictions on Gamma's exports. [B1] Explanation of the risk of retaliation. This can harm Gamma's overall trade balance and economic growth. [B1] Explanation of the impact on trade balance.

Evaluation: The impact of trade restrictions on imported steel on Country Gamma's economy is complex and depends on several factors, including the size of the domestic steel industry, the importance of steel in other industries, and the potential for retaliation from other countries. While trade restrictions may protect jobs in the short term, they can also lead to higher prices for consumers and businesses, and potentially harm the overall economy in the long run. The government of Country Gamma needs to carefully weigh the costs and benefits of trade restrictions before making a decision. Ultimately, the best approach may be to invest in improving the competitiveness of the domestic steel industry, rather than relying on protectionist measures. $\boxed{}$ [No mark allocated in original question, added B1 for a concluding statement]

Common Pitfall: When discussing trade restrictions, remember to consider the potential for retaliation from other countries. Trade wars can escalate quickly and harm all parties involved. Also, think about the long-term effects of protectionism on domestic industries.

How to earn full marks: In the "discuss" question, make sure you present both sides of the argument with well-explained points and a clear conclusion.
